I ended up using the free Senuti 0.33. It worked quickly, and since I mostly wanted to look at the metadata it was fine. In the comments on the iLounge article, people mentioned iPodDisk as another slick alternative. The 2.0 beta uses MacFUSE to allow one to directly browse the music on the iPod with metadata. I only needed to do this once, so I didn’t try iPodDisk.
